Early big George had no stamina.
Unfortunately his early trainers Saddler etc.
Were so in awe with his punching prowess they never trained him in
"How can i win this fight if i am unable to knock this guy out"

It wasn't until the second incarnation he figured this out on his own

Not only could he give it he could take it.
When Lyle dropped him Foreman landed face first still
"He Got Up"
Foreman had amazing power even being off balance.
No Heavyweight today could stand a chance with him.
Prime George beats prime Tyson
Because Georges size and natural gifts are to much an obstacle for prime Tyson who is more skilled and better trained
Lennox can't take a heavyweights punch.
Shavers falls to George.
Shame it never happened
George's amazing natural ability to punch made his fights something special.
Before Ali proved the experts wrong Foreman seemed unbeatable.
Boxing owes much to Big George
